. The Canadian field-naturalist. Natural history. 1997 Reddoch and Reddoch: The Orchids in the Ottawa District 107 Platanthera blephariglottis (Willdenow) Lindley var. blephariglottis (Northern) White Fringed-orchid Platanthere a gorge frangee Synonym: Habenaria blephariglottis (Willdenow) Hooker This orchid is one of our rarest, having been recorded only from three very wet peatlands in the District. It is fairly conspicuous, however, with its clusters of white flowers standing just above the sedges and other wet- land plants. It is easy to identify by its habitat and by its brilliant white flowers with short-fringed single-lobed lips.

Overwintering State: a greyish green shoot beside the current year's stem in the moss substrate, rising from the stem or from a horizontal root up to 1 cm from the base; herbarium specimens show the new shoot and partially elongated roots present at anthesis. Capsules: light to dark brown, ellipsoid, typically X cm, ascending (see Figure lb); yield approaching 100% on 5 plants. Seeds: light brown to brown, released in late September to early October. Blooming Period: 12 July (18 July - 5 August) 16 August [21 records]. 46°. 45° 76° 30 Platanthera blephariglottis var. blephariglottis: â = herbarium specimen.
